Title: Fully electronic wristwatch with temperature measuring device for family planning
Inventor: RUFF WOLFRAM DIPL ING
IPC: A61B10/00
Filed: 1982-12-23
Abstract: The time selection method of periodic sexual abstinence described by Knaus and Ogino is modified by this automatic measurement of the skin temperature in such a way that it offers a reliable method of contraception. The period of sexual abstinence is shortened to such an extent that this method becomes reasonable and acceptable: 5 days instead of 10 as by Knaus/Ogino. The biggest advantage is achieved if children are desired because the few hours when impregnation is possible can be optimally utilised if the time of ovulation is known exactly. Irregularities in the temperature profile are very quickly recognised and represent an excellent diagnostic aid for the treating physician.   Overall, this proposed wristwatch represents an aid that enables millions of women to experience the longed-for joy of motherhood and, in addition, contributes to halting the worldwide population explosion.
Patent DE-3300070-A1 (DE)
Title: Energy pile for heat recovery
Inventor: LAUDE FRITZ
Filed: 1983-01-04
Abstract: It is known that heat pumps serve to recover energy from the air, from running water or from ground water. This is a reversal of the refrigeration process in practice. Although the ground contains much heat energy, its utilisation is only possible in a roundabout manner. However, the utilisation of heat from the ground is also possible by means of a concrete pile if the evaporator pipes are concreted into it, the thermal conductivity of the concrete is increased, and the ground moisture is kept high by the supply of rainwater. The thermal conductivity of the concrete can be very greatly increased by the admixture of metal chips. A multi-stage compression results in a very favourable degree of efficiency.

Patent DE-3325619-A1 (DE)
Title: Line-measuring instrument
Inventor: GERBER ERNST
IPC: G01C22/00
Filed: 1983-07-15
Abstract: The line-measuring instrument has a housing (1) and a tracing indicator (5), so that it can be applied directly to the object having the line section to be measured. When the instrument is moved in a translatory fashion, the line section is measured with the aid of a drag wheel (28), the indicating error which occurs during measurement of curved lines and is to be ascribed to the distance from the drag wheel to the tracing indicator being compensated by a correcting device (36-43) which evaluates the pivoting movements of the drag wheel (28) and thereby undertakes a mechanical rectification of these movements. <IMAGE>

Title: Composite material based on fragments of vegetable origin and process for the production thereof
Inventor: BARES RICHARD DIPL ING
IPC: C08L97/02
Filed: 1983-11-18
Abstract: The invention relates to a composite material based on pieces or particles based on lignocellulose, for example wood elements, veneer sheets, woodchips, wood shavings, tree bark, maize cobs, maize stalks, straw and the like, which contain polysaccharides, lignin, tannins, essential oils etc. and are firmly connected together. The process according to the invention for producing this composite material is based on applying an activating agent, especially sulphuric acid, to the starting material, the action of which transforms the polymeric matrix material into active monomers. Excess activating agent is neutralised if necessary by the addition of a deactivating agent or neutralising agent, for example of pulverulent urea. Subsequently the activated parts are brought into contact with one another and compressed with the supply of heat, the activated monomer material being repolymerised to form a polymer of similar structure to the matrix of the starting material with crosslinking, causing the particles of the starting material to be bonded together. The activation effect can be increased by addition of a catalyst, for example potassium permanganate. The binding effect of the binder produced from the matrix material of the starting material used can, by the addition of furyl alcohol, furyl aldehyde, furyl acetone or phenols or of precondensation products thereof ...

Title: Temperature control device for forced circulation cooling systems, especially for internal combustion engines of motor vehicles
Inventor: WAHLER DIETER DIPL ING
IPC: F01P7/16
Filed: 1983-11-19
Abstract: A temperature control device for internal combustion engines is proposed, which in the area of the internal combustion engine exhaust or inlet has two branch pipes parallel to one another, each containing thermostat valves which are connected to the radiator and are both additionally connected to the bypass line. One thermostat valve is adjusted to an opening temperature of 80 DEG C and the other to an opening temperature of 105 DEG C. Both branch pipes are connected by way of a control valve, which can be switched to one or the other, to the internal combustion engine inlet or exhaust. The branch pipe containing the 80 DEG  thermostat valve is open at full load whilst the other is then closed. The branch pipe containing the 105 DEG  thermostat valve is open at partial load whilst the other is then closed. Switching over is performed by means of the control valve as a function of external, engine-related variables, such as intake pipe vacuum, accelerator pedal position or the like. Improved adjustment of the operating temperature to the engine load condition can thereby be achieved and hence an improved utilisation of fuel with significant savings.
